I don't know if this is specific to the server I'm running on, but the issue I'm having with the white screen is with larger file sizes. If I attach a <2MB pic...it's fine. Tried a 2.8MB pic and white screen.The bigger the image, the more resources required to process it. So small images will be OK with less memory.
3.2 is better than 3.3 in this regard...in that I can attach larger sizes...but even with 3.2, when I tried to attach an 8MB pic, I got the white screen.
Is that a limit with my server or with SMF? Would like to be able to use this mod with larger file sizes...at least up to 10MB.
I also have a mod that reduces the file size and resolution of attached images. This was so members didn't have to worry about reducing pics on their own (some are not technically savvy) and so I didn't have to worry about filling up my server storage anytime soon. But it appears that this mod starts processing before the file size mod kicks in.
