Cathie posted some pix of her set-up on the open group. She is testing the waters for us and the result ids that I have on my computer tiny pix.They are so small I can't see any details and clicking on them does nothing. Trying to see things in tiny picture can't turn my hair white overnight but sure feels like it could.
So I've investigated what are options are to get larger pictures on Weavolution. If you are inserting images in post or comment make sure that the largest dimension is 600. This is the largest it can be and the other dimension will adjust automatically. Claudia made a video in inseting pictures here.
The other option to get larger pictures is to post them in projects. If the file is large enough it will give an image you can see and enlarge.
I need to see what you are doing during the class to be able to help and looking at postage sized images will not do it.
Here is at 100 x 75:
Same image 600 x 600
The size of the image is controlled in the same little box that takes the URL for the picture. Below the URL is a line for dimensions.
Here is the same image in projects.
I think the limit for file size for images is 2 MB.
