Tracee - not the best person for instructions, but here goes !
Go to relevant section (ie particolours/solids etc)
At top of screen there is a box that says 'admin options' and if you click on the arrow on the right you will see 'add photo/photos'
Click on 'add photo'
Click on 'Browse' and search for your file
Caption - give it a title
Description - add anything else you like
Uploaded by - put in your COL user name
Click on 'Upload'
Hope I hav'nt forgotten anything and that it works !
