TIP If your files are really big, uploading just isn’t practical (and it might fail halfway through). For example,
it’s probably a bad idea to upload files straight from your 22-megapixel digital camera. To save time, scale it
down in an image-editing program first.
TIP If you plan to upload your picture using the drag-and-drop approach, here’s a valuable shortcut. Instead
of clicking the Add Media button to get started, just drag the picture right onto the post editor in the Add New
Post page. WordPress will open the Insert Media window, take you to the Media Library tab, and start uploading
your picture. You can then carry on .
TIP If your text narrates your pictures, you probably want to choose None for the alignment so you can position
the pictures exactly where you want them. Examples include food blogs with pictures of meals, travelogues
with pictures of tourist sites, and home renovation stories with a photo journal of the step-by-step process. On
the other hand, if you have a rich layout that’s more like a glossy magazine, you might decide to use Left or Right
for your picture alignment.
NOTE In addition to storing the original file you upload, WordPress creates three extra versions of every
picture: a 150 × 150 pixel thumbnail, a 300 × 300 medium-size image, and a 1024 × 1024 large-size pic. You
can change these defaults in the Settings→Media section of the dashboard, under the “Image sizes” heading.
However, the changes affect only new pictures, not the ones you’ve already uploaded.
NOTE When you edit a picture, WordPress actually creates a new file. If you look at the picture’s URL,
you’ll notice that WordPress appends a number to the end of the filename, so dead_elvis_tattoo.jpg becomes
dead_elvis_tattoo1339626522667.jpg, for example. There are two reasons for this sleight of hand. First, it prevents
problems if one of your posts needs to use the original version of the picture. Second, it lets you get your original
picture back later if you ever need it. To do that, edit the image, and then click Restore Original Image.
NOTE If you delete a picture from your post, it still exists on your WordPress site. This might be what you
want (for example, it lets you use the picture in another post), or it might be a problem (if you’re worrying about
someone stumbling across an embarrassing incident you made the mistake of photographing). To wipe a picture
off your site, you need to use the media library
