 Hey guys,

 With the new release and the addition of the srcset attribute, the lower
 res 150px x 150px images are causing pretty hefty pixellation on some
 devices.

 If for example you look at featured images using the post_thumbnail
 function on an iphone 6 they look really pixelated as it is grabbing the
 150px image and upscaling it.

 I have attached a screenshot, I basically think that the 150px on smaller
 devices may be a little bit harsh, and there should be a minimum size of
 perhaps 280 - 300px (around the width of most smartphones)

 If you look at the product images on the this page -
 http://staging.eightarms.co.uk/tabcat/shop/ on an iPhone 6 you will see
 what I mean, be interested to hear your thoughts as I'm worried that on a
 lot of newer devices there are going to be some pretty chewy looking
 images.

 I totally understand the need for quick loading times etc..but I think
 there may be a better compromise, or the ability to set the minimum size
 would be very useful rather than having no choice in the matter and having
 to accept 150px as the best size.

 Look forward to hearing from you.

 Matt
