No way!
I was uploading my 4 shots yesterday and I got to 3 when I tried uploading the 4th it kept telling me this message
"The file extension you have entered is incorrect"
even though it was a Jpeg.. it took me ages to work on that and now I know why it wouldnt allow me to upload a 4th on the trot!
Not to worry, I agree there should be a photo cap for uploads.. I just forgot you'd added one. I've voted for 3 well because that is what it stands at the moment and it's always been a good base for stories.. beginning, middle and end.. I think with the right imagination you could stringe a sequence of pictures in 3 and still have an awesome upload, without flooding the page.
The problem here is that if someone really wanted to be an Ahole.. they could upload 3 and wait for someone else... upload another 3 and wait for another upload.. then upload another 3. Technically it's not flooding but when the page is expanded you'd still get 9 or 12 of their shots to someone elses 3 so it sort of doesn't solve that page issue thing.
