He was cursing from time to time (actually - all the time!) because this site let you download, but the download was one of those "SAVE" (all dossiers) which means that if you only want the photo, you'll have to convert it later with an Editor - boring and long when you've got hundreds of photos ro do!
I informed him about a little tip, and he thought I was "nuts", but he tried it, and felt really stupid when it worked...!
Here it is for those of you who don't know it already:
When you download, in the box for the name/title of the image, just tap " .jpg " (without the inverted commas, but a . at the beginning, of course) at the end of your chosen title, press "SAVE" and watch it download as a .jpg image!
If you use this to change other formats, lik .gif for example, you are probably destroying what you wanted in the first place, because .jpg images don't move.....!
