Welcome to the board, Daphne. You have a stunning resource in the members here. Although your interest is not one I can claim even the smallest expertise in, I am confident there are many who can and will help you.
Just a few ways in which it is best to make requests.
1. Always limit your request to one item per posting. That way a specific reply can be made without risk of confusion.
2. You need to provide clear photos. Usually more than one is best since the base may provide clues as to who would not have made something(for instance). I normally try for a general shot of the item, a profile shot, a clear shot of the base, and another of a signature or mark if one is present. You will notice that you can post up to 4 attachments to each topic response.
3. You will need to learn how to crop and/or resize your photos to reach the individual size limit of 125MB and there is also a dimension limit of 999. So a photo of size 1238 x 367 would not be accepted. I achieve this by using Microsoft Office Picture Manager which is inbuilt in my Windows software. A typical "bland" photo will be around 650 x 650 but a "busy" one may be nearer 400 x 400. You should play using Save As to make multiple versions of your original photo and then experiment with the effect of sving your trial resizing/cropping experiments. All one has to do is save the changed version, then simply put the mouse on the new version and the size shows up for you.
4. Finally the last piece of advice
