I was curious what could be causing difficulties with posting photos..so I tried to post..this is what I learned:
Steps to making an AD with photos.
This is to help, sorry if it anyone doesn't want/like it-let me know.

1. Log into your account
2. Choose "Create Content--then Advertisement on Right menu
3. Choose best category/categories, this will help people find your listing when it's not "new" by looking through the sorted categories
3. Type your description into the "Body"
4. RIGHT BELOW the body area is a small arrow and "Input"--Click here.
5. Choose filter (the topic will expand) -If you have photos, use the 2nd (Full HTML) version..click the circle to fill it.
6. Under "Attach new file" click the "Browse..." button.
7. After you select a picture from your computer..click "Attach"
8. Click "Preview"..this usually only shows text..may show thumbnail of previously added pictures.
9. If you're happy with the preview, click "Submit"

If you have more pictures to post, repeat, using the "Edit" button in your Ad.
*Be reasonable about image size..600x800 is plenty big enough and will be easier to post-even if the server script is programmed to resize, it uses RESOURCES which slow down the server and increase bandwidth demands, which can increase the cost of hosting..depleteing funds that could go the the Young Writers Project.
