Using Woobox’s Static HTML Iframe App on your Facebook Page?

If you are using Woobox’s Static HTML IFRAME App on your Facebook page like me you may want to keep an eye on your pages to make sure the App’s images are displaying properly.
 

Woobox has had numerous customers tell them that page tab images are randomly changing to another page’s custom tab image. This is happening without any interaction. After a tab image is set, sometimes when you go back to it later the image that appears is different.
 

Here is what they believe is happening: There appears to be a limit of 10,000 tab images for a Facebook app. When a tab image gets uploaded a number between 0 and 9999 gets assigned to the tab image to use in the image URL. The last part of the image URL is what seems to be randomly allocated and limited from 0 to 9999. For apps with large numbers of users like the Woobox Static Iframe Tab, users quickly fill up the allotted 10,000 slots and when new tab images are uploaded, it overrides an existing tab image which then changes the image on the original page. It also prevents you from seeing the new image you upload since it is cached on their servers with the old image for a period of time.
 

Luckily they seem to have found (or hope that they have found) a solution; using these instructions you can easily create a Custom Tab Icon using Woobox’s IFRAMEHOST. Frankly, I’m not sure why I didn’t do this to begin with, using the custom tab icon gives you a much more professional looking link.

 

Tips
  • Find a good “square” icon to use for your app (i.e. 16 x 16, 32 x 32, etc.)
  • Replace the default App Image with one that is 111px wide by 74px tall — this represents the new size for Facebook’s new page layout.

 
Update: 3/26/2012 – I just noticed that if you want to utilize the new 810px width settings you may have to go back to developers.facebook.com/apps/, then select your app, edit. Then under page tab width, select 810px.
