Hello Colin,
This is a repeat of the "How to Post Pictures" detail given in the FAQ section of the Forum:-
The simplest way to upload pictures to your profile is to log in and click on MY ACCOUNT
Then, in the sub menu, click on SUBMIT ITEMS then UPLOAD PICTURE
As a guideline, images are best when sized at 800 pixels by the
longest side, at 72 dpi and they MUST be jpeg format. You can upload
images of any size but please bear in mind that your page might load a
lot slower and that it will use up more of your account space
allowance, particularly important if you are a standard member.
Make sure you select the IMAGE CATEGORY appropriate to the style of picture you are uploading.
After you have successfully uploaded one picture you should be brought back to the "Upload Picture" page and simply repeat the process with your next picture.
If you find you have made a mistake you can delete your picture in MY ACCOUNT / MY ITEMS / MANAGE PICTURES.
Hope this helps,
Ron
