I messed around a bit, and I know one thing for sure...there is a max limit, although I don't know what it is yet.

Just for the record, nothing over 2.8 MB works. I'll narrow it down in a little while.

*edit* I just uploaded an 800x600 PNG that was 755KB to it, and instead of loading it, like a normal sized PIC1.png, or not loading at all, like a 1.5mb PNG, it tried to load it, but instead loaded up a gray screen like this:

Note that there's no description, just an icon and a gray screen.

This is what I get if I try to load a 1.17MB PNG(1024x768):

Instead of loading a picture, it only loads the description.

Still working on it...
*edit* I forgot, here's teh totally random picture I'm using as a source:

A Genesis, and a can of Cherry Vanilla Dr. Pepper.
Can't get much more random than that.
Obviously, this is scaled down, the original is a whopping 2560 by 1920. It's 16.5 MB in size.

Also, I uploaded an image that was 640x480, and it's size was 488kb.

It did like the 800x600, no description, only now it's got odd lines going through it. I'm beginning to think it's a resolution thing.
*edit* Okay! I think I've narrowed it down! I uploaded a 512x384 that was 301kb, and it loaded!

I have now come to a conclusion:
The max size is approximately 300kb, give or take a few kilobytes.


And, before you ask, yes, I have no life. That's why I waste time doing stuff like this.

Thanks for your research!! Since there is not guide needed on how to make these (self-explanatory) no one bothered finding out the limit.
