only partially. There have been some longstanding issues with guys posting reviews using the review template, but the issue regarding posting photos for ads has only come up recently, and I don’t recall seeing anyone mention it being exclusive to Safari users.
If you’re able to create an Album in your profile, you might try posting there. Ck1942 noted in another thread that some ladies had begun doing that and they were then able to copy them over to their ads/WW posts. I’m sorry I don’t have the link to that particular post, but hopefully someone with more knowledge can chime in here.
