This is quite a great tool with such great features as you clearly stated as above, and I'm happy we now have a forum friendly image hosting tool that can enable us to both crop our image and also automatically reduce its size to the maximum allowable size which is 2.5MB..
However, I just tested this tool and I noticed that there are 2 things I observed about it, and I will be happy if resolved amicably. And they include as follows.
1. I uploaded an image with a size of 2.83MB, of which I know that it's above the maximum size of 2.5MB, but I went ahead, trying to use and test the new "Resize" feature on this site, but instead of it to resize, it keeps displaying
"could not process image". as shown below... So am I the only one experiencing this, or it is general?

2. While secondly, another thing I observed is that while trying to Upload an image, I noticed that I can't select more than one image at a time.i had to upload the images one after the other. So imagine if a person 20 has images to upload, that means he will have to go 20 times each by uploading one after another.

So I will be glad if these can be checked.. thanks
