Example 1: My images get scrunched or chopped off.
The maximum size you can have an image in a post without it breaking your theme’s layout is found in the FAQS. Firefox will try and resize image to fit. Internet Explorer does not bother and a large picture will usually send your sidebar to the bottom of the blog.
Example 2: I can’t figure out how to size my photos correctly. I size them down to the correct pixel sized designated by the template, but after I upload them and check “full size”…..they’re HUGE!
You can resize your images after inserting them into a page or post. Click on the image and then grab one of the corner handles and drag to resize. Using a corner handle will retain the height to width radio and not distort the image.
You can also resize images within the WP editor. To do this you can either click and drag the corners, click the little tree-in-a-box icon, or use the Code tab to edit the raw HTML. If you do the latter you can effect image resizing by changing the height and width tags within the image tag.
Example 3: I can’t find the thumbnail option. I am only offered the full size option, which is too large for my blog.
When you upload an image you normally see a thumbnail of the image and you can use that as a link to the larger image. If it is missing the image is too large. An image should be 2000 pixels on it’s longest side and then you will get a thumbnail.
Read the details here Where is the thumbnail?
Example 4: I wrote a new post and uploaded 6 images in it. These images had the same names as some previously uploaded images and any images which were in previous posts where the picture had that same name are now displaying the images from today.
When you upload an image that has the same name as an image that was already uploaded, WordPress should automatically rename that new image by appending an number on the end. The only way you should be able to upload an image with the same exact name is if you delete the old image first.
Example 5: I cannot upload images – why?
The most likely causes are:
- The image is too large (filesize)
- Your connection is slow
- There is a problem between your computer and the WordPress server.
