INTEGRATING IMAGE RENDITIONS AND PAGE LAYOUT

1 - 8 . (canceled)

9 . A system comprising:

one or more computer processor circuits configured to:

create, based upon a set of image rendition parameters, a set of image renditions for an image;

select a set of previews to display, each preview in the set of previews including a markup language file and breakpoints that specify how to display a particular image rendition from the set of image renditions;

create a rendered instance for each preview in the set of previews based upon the particular image rendition and page content identified by a corresponding preview;

display the rendered instances as part of a user interface;

receive instructions from the user interface and that specify modifications to a particular preview of the set of previews; and

modify, based upon the instructions, a markup file corresponding to the particular preview.

10 . The system of claim 9 , wherein the one or more computer processor circuits are further configured to:

identify violations of preview layout rules caused by the modifications to the HTML file; and

adjust breakpoints associated with the particular preview based upon the identified violations.

11 . The system of claim 10 , wherein the one or more computer processor circuits are further configured to:

identify at least one gap between breakpoints associated with previews in the set of previews; and

select a set of additional previews corresponding with the at least one gap between breakpoints.

12 . The system of claim 11 , wherein the one or more computer processor circuits are further configured to:

create an additional rendered instance for an additional preview of the additional previews based upon the set of image renditions;

display the additional rendered instance as part of the user interface; and

modify an HTML file and a cascading style sheet file based upon input from the user interface.

13 . The system of claim 12 , wherein the one or more computer processor circuits are further configured to select the set of previews to display by selecting previews that correspond to display capabilities of a predetermined set of devices:

14 . The system of claim 9 , wherein the instructions include at least one instruction selected from the group consisting of cropping, resizing, and replacing, relative to the particular image rendition.

15 . The system of claim 9 , wherein the instructions specify that another image should replace the image corresponding to the particular image rendition.

16 . A computer program product for authoring web pages, said computer program product comprising:

a computer readable storage medium having stored thereon:

program instructions executable by a computing device to cause the computing device to:

create, based upon a set of image rendition parameters, a set of image renditions for an image;

select a set of previews to display, each preview in the set of previews including a markup language file and breakpoints that specify how to display a particular image rendition from the set of image renditions;

create a rendered instance for each preview in the set of previews based upon the particular image rendition and page content identified by a corresponding preview;

display the rendered instances as part of a user interface;

receive instructions from the user interface and that specify modifications to a particular preview of the set of previews; and

modify, based upon the instructions, a markup file corresponding to the particular preview.

17 . The computer program product of claim 16 , wherein the instructions include at least one instruction selected from the group consisting of cropping, resizing, and replacing, relative to the particular image rendition.

18 . The computer program product of claim 16 , wherein the instructions specify that another image should replace the image corresponding to the particular image rendition.
