As for image uploads being streamlined I'm sure we can make it better than uploading to Photobucket and pasting across the link. If TMF needs to host the images itself then we will have to throw some money at it and get some storage set up to handle that sort of data.
That could work, but surely it would cost a lot of money? If people used it instead of PB, surely there would come a point where they use up all of their allowance? They would then start to delete pictures. When you go through old threads and find deleted and missing pictures, especially in the projects section, it would soon become annoying.
I think PB or any of the other sites works well enough. it would just be a lot better if you could simply select multiple images in PB, press IMG tag once and be able to paste the whole thing into a post on here. Obviously that is something PB would need to sort and not here but would make it work a lot better.
