There is an attachment feature available to users in the For Sale forum that allows uploading of images. The image size limit is small but the feature works really well. The initial post will have a thumbnail of the picture and a link to the full image.
That is the preferred method. We get a lot of requests from folks to set up albums (and a lot of well meaning but misguided suggestions from long time members for them to do so) solely for the purpose of posting ad pictures. That eats up a lot of time for the old guys running this place as well as a lot of server space that the old guys pay for. We still do it on request, however, and the old guys rarely complain.
These albums are put in the For Sale section of the gallery (inside the CBTech Library main album) with the idea that we will remove them when the boat is sold. I haven't done it for a while so there are lot of them. Users can also post individual photos to the For Sale album and embed them in their ad posts without the need for a dedicated album. Quite often, a member will request an album without letting us know it is to accompany an ad and we put the album into the main owners gallery where it often time sits unused.
One of these days we will upgrade the software and format of the C-Brats web site, but that will entail a lot of changes that this particular old guy may not be up for. Will has talked about it several times in the past and I have never discouraged it, but I have not encouraged it either. There will come a time that we won't have a choice, I'm afraid.
By the way, Will (Da Nag) and I are the old guys mentioned here and for or now we just keep plugging along.
