Shander, the help section here has a couple of really good stickied threads on how to post photos. I use a different browser and have a lot of protections on my system and still had problems until I found the site linked below, my main issue was the file size is too large. If you are using a phone, you can usually easily send a photo to yourself, that should also reduce size but those help sections will help!

For me, I use this free webpage that does not set off my browser protections. Hubby is starting to want to upgrade cameras for easier posting than our early digital model.

I have a lot of fabrics with butterflies and dragonflies mixed and would be glad to look but a picture would really help. Also the amount of fabric you are looking for, if you need a small piece I might have it. If you need a large it is really unlikely but I have one that might be in your description...
