So that's the JPEG file format and it does have some pretty appropriate uses and pretty good use. However, we have the last one, which is the PNG or P-N-G. The PNG file format is going to come in basically two main varieties that you encounter on the web. You have a PNG 8 and you have a PNG 24. Now, the PNG file format is lossy, meaning it's not going to be deleting pixel information, kind of like our JPEG does. Now, not only is the PNG a lossless file format, so is that GIF file format. So both GIF and PNG are lossless file formats. So they're not going to be losing information. Now, the PNG 8 is going to behave a lot like our GIF file format and our PNG 24 is going to behave a lot like our JPEG except with the PNG 24, we're going to be able to have alpha-level transparency, which means if we have an object that has a semi-transparent background to it, the PNG 24 is going to be maintaining those levels of transparency. Now, the PNG 24 and the PNG 8 sound great. Why even bother with the GIF or the JPEG? Well, one of the issues with the PNG file format is typically those files end up being larger just by the way that the information is encoded into the file itself and the fact that we're not deleting pixel information. So there is some tradeoff between all three of these different file formats and depending on the content you are trying to save will determine which file format you will save for web. So what I'm going to go ahead and do is I'm just going to go the File Menu and I'll do Save As and I will save my banner out here as a GIF file format and whenever I click save, it's going to go to work saving and it will present me with the dialog box asking what I want to do. I'll go ahead and save as animation. I'll convert to index using default settings and click Export and here we have our Save as GIF Options that we discussed previously. Now, the option that I want to change here is I want to uncheck Loop Forever and I'll leave the default to 100 milliseconds for frames where I haven't specified a time and then I'll just click Save and it goes to work and again we can preview this by going to the Filters Menu, Animation and Playback or I can do Repeat Playback if that was the last thing I did. And so there we go. It looks like a fairly smooth animation and of course, what I'm seeing is that it is looping but because I unchecked the Loop Forever, it's just going to play once and then stop because a continually-looping animation on a website tends to be kind of annoying. But anyway, that's how we're going to save our animation out to the web and some other consideration for other images you might be working with.
