I'm using a portfolio theme, which adds several images for a project.
For example I have 3 projects P1 P2 P3 each one with 3 images P1i1 P1i2 P1i3 P2i1 P2i2 P2i3 P3i1 P3i2 Pei3
P1 - Project1 / P1i1 - Project 1 image 1
The images usually appear in the order of the upload, but ... let's say I delete image2 from Project2 ... we will have P2i1 and P2i3 only.
Now when I upload P3i1 P3i2 P3i3 ... instead to appear in this order it starts something like P3i3 P3i1 P3i2 and I don't know why.
I suppose if the images have id's like 1/2/3/4/5/6/7/8/9 ... deleting and image will place the next one in a missing hole or something ... 1/2/3/x/5/6/7/8/9 ...
How can I see each image index and eventually to change that, or before to upload other images after I delete an image from a previous project to rebuild somehow the index to not have missing id's in between.
