It's better viewed on a larger screen, in the office or home where there's no per-megabyte charge or limit.

I think you are assuming they don't know how to turn off pictures and flash in their mobile browser ?

Except they aren't suggesting uploading the same to both - they are suggesting uploading a downgraded version here. A back up of a tiny, heavily compressed file is not a back up.

It also isn't helpful - let me explain what helpful is. My camera can take very sharp 16MP picture of things about 20mm across. I can view this on a 24" screen and see things I can't with a magnifying glass - that's helpful. Macro photography is very helpful in this hobby. Small, compressed images are only "helpful" to low bandwidth users because they don't have to wait ages for a high quality image to load.

I want high quality images and I encourage others to take such photos and post them. It's a total waste of time to upload crap that doesn't help people see solder issues etc.

I'm sure we all agree we can cope with the inconvenience of a missing image when others are struggling with such disasters.

Now you might argue that I'm being inconsiderate by not catering to a reasonable request. Turn that right around - it's inconsiderate to ask people not to make full use of the technology that's available these days, just because a few people can't.

If its absence diminishes the value of the post/thread/forum, any temporary graphic should be avoided IMO. Large hi-res graphics can be a perfectly acceptable alternate to "getting the point" graphic post attachments.

I get where you're coming from, but does it mean if you and I should meet I should only text you from across the room? To phrase it in a neutral but meaningful way... Is technology without humanity desirable?
When the situation calls for macrophotography, it should be understood as such. When available technology allows improved optional access, why not make use of it? While also avoiding multiplied inconveniences? Multiply choices instead.

I think some of you are thinking it backwards.
*Attached* pictures are the ones that take up DIY server space and "eat" its bandwidth; those hosted elsewhere do NOT.

The DIY page only holds a tiny (a few *bytes*) link pointing to the actual picture address, and the guy who's reading the page gets the "light" HTML from DIY and the "heavy" picture from the external server.
It does not go through DIY in any way.

FWIW I sometimes draw or post schematics to illustrate some point, but I *always* edit them in IrfanView to: GIF, 1 bit which means only black "china ink" on pure white, no greys.

Sometimes I refer to a very poorly scanned schematic (such as an old Gibson or whatever) and reducing to 1 bit destroys part of the image, so in that case only I reduce to "16 grey".
My schematics are real sharp and readable and same KB size or smaller than the JPEG version.
In fact JPEG, a *colour* picture standard, must not be used for black on white detailed images, such as schematics or mechanical blueprints.

This is an example:

Click the image to open in full size.

It's a large image, originally 1565x486 px.

In *this* particular case it's unnecessary, because the schematic is very simple, but if it were , say, a JCM90, a Twin Reverb, a Randall or similar or higher complexity schematic, it would be the *minimum* size or it would be unreadable.

Now, how does my "huge image" tax the system's resources?

Let's see what unjustly dreaded Imageshack says:

Quote:
Location:http://imageshack.us/a/img15/9496/12ax7tester.png
Type: PNG Image
Size: 8,64 kB (8.848 bytes)
Dimensions: 1.565px × 486px (scaled to 986px × 306px)
8.64 KB !!!! <<<<<<<<<< !!!!!!!!!!!!!!!!!!
Where's the system overload ?

And as I said before, It does not come through DIY at all.

What you must set your sights on, is on clueless people (99,9% by the way) who take amp or guitar or even a simple ceramic cap pictures at camera's max resolution, ("hey!! I bought a 12MP camera, now I'll use it") and post them as-is.
They don't even notice it, because Browser software by default resizes them to screen size .... burning its neurons in the process plus wasting all that bandwidth.

But a properly processed image such as the ones I post should not be frowned upon, quite the contrary.

And as mentioned by others, besides holding rights on them, there's the very practical posibility of being able to edit them, often to show a schematic voltage or part value change or focusing on another point in the same schematic.

Why not upload and hold them here, at DIY?
Not sure about what happens here, but many times in other Forums the software they run automaticaly resizes images ... making schematics unreadable.

I think that if you want to keep byte size under control, you should keep track of *byte* size ... and that for those actually hosted here, but not for *pixel* count which can be very efficient, as I have shown above, and absolutely necessary for readability.

As a suggestion: you *may* add a requirement that "images larger than xxx by yyy pixels must be in .gif or .png formats" which are lossless and keep sharpness, plus being quite compact and free from artifacts.

This will automatically sweep away clueless people.
Those who have no idea of what picture size means, will be even less able to convert formats and reduce color depth.
Just an idea.

Sorry Jim, you're wrong on this one. If you had read the thread, you'd understand why.

Your example, however, is the exception. It's a well done, small GIF that is easy for just about anybody to view. The vast majority of images posted to the forum are NOT like that.

Yes, some forums do, and it's frustrating. This forum does not, as has been shown numerous time in this thread a throughout diyAudio.

And your example still does not solve the problem of disappearing images, which has been a big problem here.

I was going to post some pics of the DIY high power LED light I am building when I came on this thread.

I see I am guilty of posting linky (flickr) pics of all my projects and I will not make that mistake again.

I just won't post anything anymore. Please delete my account.

Default Big Pix,s

Not to be mistaken for Big T... lol (Triodes!) Where is your head at? I agree with pano's reply #6 I do NOT know how to use my camera and wished I could post pix's as I feel it would better explain some of my Q&A.
I recently bought a camera via ebay. Though new, It takes for granted all of us out here is up-to-speed on modern tech. Getting my photos down to an acceptable size is my problem. Call me old school, but I do need a link to a tutorial on this vary subject!

You can do it at the camera or at the computer. All you need is someone to show you once and you can take it from there. If you are an a mac, it's as easy as pie in iPhoto.
