There is a relatively simple(ish) way to make it a bit harder on your end but easy-peasy and seamless to everyone else. The next time their pages load, your new button will appear, with no effort on their part. Much easier than sending out pleas to change the code, yes?
The trick is to upload your new button to your web hosting site using the same file name, which will therefore give it the same URL as the old button.
Note: This trick will not, as far as I know, work if you've uploaded your image to Blogger or Flickr, and I don't know if it works on WordPress-hosted images. Which frankly is a good enough reason to advise you to use Photobucket for important images, so you have more control. If you host your own images on a server, then the following tips can still apply — but you probably already knew how to do this.
How to keep a direct link in PhotobucketFor instance, here is the HoboMama.com blog button:
Here is the direct link for that image:
The piece of information after the last slash is the name of the image file, so hobo-mama-button-200x200.jpg
If you wanted to upload a new picture but keep the same direct link URL, here's what to do, in this order (very important):
- Create the new image in your photo-editing software and save it with the same name as the original (e.g., hobo-mama-button-200x200.jpg).
- Go to Photobucket and find the image you want to replace. Click "delete" on the old image, acknowledging that you will be breaking all the links that are looking for this image (but only temporarily!). Make sure you have a backup of the image on your computer in case you want it in the future. (Optional: You can always re-upload it to Photobucket with a different file name [for instance, rename it hobo-mama-button-200x200-archive.jpg before uploading] if you want it archived online.)
- Upload your new image to Photobucket, in the same folder as the old one. The new direct link will be the same as the old one (http://i233.photobucket.com/albums/ee159/lintpicker/Elements/hobo-mama-button-200x200.jpg), as long as you were careful to name your file the same as the old file.
It's important to delete the old image before uploading the new image. Otherwise, Photobucket will rename the new file slightly to differentiate between the two and the direct link will be different.
And, again, if you have different folders within Photobucket, make sure to upload to the same folder, since that becomes part of the URL as well (Elements/ in my example).
This trick comes in handy for regular blog buttons, but also for advertisements and giveaways. Say you wanted to advertise on someone else's blogs, such as for your Etsy shop. You might make your ad seasonal but do all the changes on your end. So, you could create an ad with summer products, and then easily switch it out to winter products later in the year. As long as you kept the file name the same (e.g., hobo-mama-ad.jpg) and deleted the old ad image, you wouldn't have to have your advertisement hosts change their code at all to be current.
Or, for a special giveaway event, such as some review blogs do — a baby shower bash or a holiday-themed event — you could name your button for that something like hobo-mama-reviews-giveaway-event.jpg and then just keep updating the image but under the same name each time. That way, your event button on people's blogs would never be out of date!
Hope that helps, and that all your bloggy fans will appreciate the new image that magically appears on their screens!
