flickr & Popfly

I played a little with popfly to create a carousel stack of my images based on tag(s) from flickr, and well, had quite a few issues...firstly, the built in flickr block doesn't allow returning user images based on tag, so I ripped the flickr block and created mine. Had some issues with the block not allowing me to enter the flickr key for this block, so I hard-coded the key in the js file itself! The other thing is you can't pass querystrings to your mashup; so there is no way you can customize the mashup at runtime (well, in a way you can by using the user-input block; but that doesn't solve my problem). Anyway, creating the mashup was really straight-forward and given that popfly is in early alpha stages, I guess it will only get better.

Update 6/12: Played around with popfly a bit more and learnt quite a few things, which you might want to know:

  • There is no way to pass querystring parameters to a mashup currently, this means that the mashup cannot be dynamic w.o. requiring user input: this will be implemented in next release.

  • Some blocks like Carousel and Photo Sphere have rendering issues in fx and don't display at all on that browser: again something which will be fixed in next release

  • You cannot really "rip" a block which requires a developer key and extend it, or more generically, you cannot create a block which requires a developer key unless you are willing to hard-code your key in the javascript itself.

Here's the link to the mashup.
