How do I upload from an IPhone or IPad?
"I-phone/I-pad users should now see a specific set of instructions, on
the edit photo page. Below are the steps for uploading from an i-phone.

Click the edit photo button on your account page. on the right side of
the page, you should see an address, inside a box. That is a clickable
link. the menu should appear like this...

1. Click on the address above, and copy it. (not on this post, on your
Mingle2 photo page)
2. Open the photo app on your device.
3. Select the photo you want to upload.
4. Tap the screen to bring up the on screen controls.
5. Tap the "send" icon at the far left of the on screen controls.
6. Select the "Email Photo" button.
7. Tap the "To:" textbox at the top to paste the email address
you copied earlier.

Go to the edit photos option. There's something called 'add photos' there. Select it. They will show u an email id to which u can send ur new photo from your phone. Once the photo has been uploaded, go to ur photos and click on the new photo and select the 'main image' option.

I did this but the photo I keep uploading keeps getting taken down. It's not offensive, nude or anything. Just a game character with a fiery background.

Just wondering if I might get some help figuring this out

Thanks
