Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
Even till the day of the Keynote about the new iPad, I couldnt believe the rumours telling the new iPad will have a Retina Display. I thought it was a too big challenge for the Apple engineers to make a resolution of 1536 x 2048 pixels was workable for a mobile device. I was waiting for Apple coming with some smart solution to up the screens resolution, without doubling the size in both directions. Apple actually surprised me by releasing the new iPad with this ridiculous big screen. As a user, this was off course fantastic news! As a developer, just doubling the size of my artwork wasnt enough.
When I started working on my first app update to support the Retina display, I found out the hard way that just doubling the size of my images and including them as @2x images blew the size of my app completely out of proportion. Mosaic Wallpaper Designer currently takes 5.5MB of your space to download it from the App Store. After I have included my reworked images, it grew to around 45MB! Even though this is an universal app and most of the UI is already in Retina resolution to support the iPhone 4 and 4S.
As a coder, I had to search for some tricks to reduce file size of my graphics to make the the file size workable again. Because I dont think Im the only one facing this kind of problems, I would like to share some of my experiences with you. For people with a graphical background, this may be pretty obvious, but this article is more targeted at Independent Developers without much of a graphical knowledge.
