Hello,
In order to have space to upload pictures, I have been deleting many pictures from many of my coins on Numista. However, the website notifies me that I have used all of my memory.

For one, crop your pictures … it is not necessary to be able to read you fingerprints … only the coin. More than 90% of the image is useless.
After deleting pictures, you'll need to empty your bin on https://en.numista.com/vous/pictures.php to free space.
And if you need more space, get a premium account and support numista ;-)
Indeed cropping but mostly reducing resolution to a non ridiculous amount will save you a tonne of space.
Your average banknote (and probably coin) picture is nearly 2 MB large, with most items having two sides that gives you 250 items with the free space. With cropping and reducing the resolution to fill a full HD display lengthwise 1900 pixel you end up with around 700 KB. That's 65% less space needed and the picture quality is still more than enough especially for just being snap quality in the first place.
That would give you on average space for 360 items with two pictures (the more you reduce it the more items).
Compare original vs cropped and reduced : 1.93 MB vs 0.781 MB (in my opinion it could go far lower still)

The question is rejected
In my opinion the answers should be kept, and if possible inserted into the FAQ
