I am trying nativeads.com right now and their image size is 150x100. I didn't know that when I signed up or I would not have joined. I need to find a network with larger image sizes. I looked for a FAQ or something on Taboola but not luck. Many of the networks I visited wanted me to sign up first before they would tell me anything specific like initial deposit, image sizes, etc. Taboola seems to be in my price range. You can start at $10 a day. (native ads is $20) but I need a network that will allow 250x300 or even a little larger image. Any ideas on what network to look at.
