    <p>I'm using the Facebook SDK to allow users to share content through my app to their Walls. Its a pretty standard set-up with the Facebook SDK where a typical post will contain some text as well as an image to accompany the post. </p> <p>This all works fine, but my problem is that since Facebook resizes and converts the images as they see fit, the post images look a bit pixelated when viewed on a Retina display. Does anyone know whether there is a way to ensure that Facebook uses a higher quality image for this? </p> <p>Again, to clarify, the original images I'm using are high enough quality, but Facebook degrades them a little too much, and they end up not looking too good on a Retina display. Can we avoid this in some way? </p> <p>Below is an excerpt from the pretty standard Facebook post code I'm using;</p> <pre><code>NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: sharingURL, @"link", sharingTitle, @"name", @" ", @"caption", description, @"description", actions, @"actions", picture, @"picture", nil]; [facebook dialog:@"feed" andParams:params andDelegate:self]; </code></pre> <p>Note that the images I'm linking are roughly 250x250px JPGs, if that helps. </p> <p><strong>EDIT</strong>: Added a sample image to clarify what I mean. I'm trying to see if there's a way to ask Facebook to use a high-res image for retina displays here. </p> <p><img src="https://i.stack.imgur.com/umFwg.jpg" alt="Post image and how it looks on FB"></p> <p>Thanks in advance!</p>

    1. COWhat code are you using to grab the image and show it later in your app? Facebook stores several sizes of each picture. You can usually get the higher quality version with a simple query string parameter, but it depends on how you are getting the image back.

    2. CO@Inturbidus, Thanks for the info, but I'm not talking about getting pics from Facebook from my app; rather, uploading / sharing content via my app to FB. I've added a pic to further clarify what I need.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
