I have an issue with product's images.
When i add images for a product see (cap image) , after when i click add product i see this screen (see cap2 image).
I don't know why this is happening. I only suppose what possible creates this bug.
I usually name for each product names for images ex 1.jpg , 2.jpg, 3.jpg etc
When i uploaded these pictures with names 1.jpg , 2.jpg i had previously added products with same names but actually this shouldn't happen (to have this issue).
Also when i started to add alt texts in my upload images i observed this issue. Also i add related products (which very very possible have same names)
How can i fix this? Actually, this shouldn't happen even with same names because if the site register many vendors and add thousands products then many big sites would have problems.
