When designing websites, images-to-be-used usually doesn't exist at first as it is the layout that matters the most.

However, the sizes for the images are usually pre-set and inserting some placeholder images help us better seeing/analyzing the layout.

Rather than creating these placeholder images manually, there are free to use services which can automate the process and save us time.

Here is a list of 8 free placeholder image services for instant dummy images:

Flickholdr

FlickHoldr

As the name tells it, Flickrholdr fetches images from the huge database of Flickr.

Besides the size of the images, it is possible to mention tags in the URL which is great for using related images in each spot.

The service is full-featured with the ability to mention sizes, image format (.gif, .jpg, .png) and can also display text.

The size of the images generated are displayed on them as well.
